Customer Question

I have a Lennox CBX32MV. The thermostat reads The A/C turns on for a few seconds, then goes off. It reads Alert/Error 201. Can you help?
JA: Just to clarify, do you think this is a larger HVAC problem, or something specific to the thermostat?
Customer: Not sure what 201 indicates. I only know that it's 80 degrees in the house.
JA: Do you plan on doing the work yourself?
Customer: Depends on what's involved.

At the end of our dialog, you will have a chance to rate my service, but please wait until we are finished and you're satisfied you have all the information you need. Please be patient as many times we work with several customers at once.

Have you tried turning power to indoor unit off, then back on after a few minutes?
